Definitions
- the present invention relates to a method, and an arrangement for optimizing the operational readiness times and cell change performance of mobile terminals as used in a cellular mobile radio system, for example according to GSM or UMTS standard.
- the cell change occurs in idiom mode or in certain stages of connected mode in UMTS (URA_PCH, CELL_PCH and CELL_FACH) by a mobile device based cell change algorithm.
- UAA_PCH UAA_PCH
- CELL_PCH CELL_FACH
- the radio network informs the corresponding terminal about potential neighboring cells via the so-called broadcast channel (BCCH).
- BCCH broadcast channel
- Control of the radiated neighborhood cells is the responsibility of the network operator.
- a large number of possible neighborhood relationships can be emitted, which can also include neighborhood cells of another radio access technology (GSM, UMTS, cdma2000) or frequency (for example in the case of UMTS).
- GSM radio access technology
- UMTS cdma2000
- Extensions for existing mobile technologies can also enable the announcement of further technologies (eg WLAN, WiMAX, etc.) on the broadcast channel of, for example, UMTS [DE10302404A1].
- the following statements of the prior art relate primarily to a GSM and UMTS standard application.
- mobile radio terminals are obliged to measure configured neighborhood cells either continuously or with a defined periodicity in order to trigger a potential cell change on a better radio-cell.
- this technical specification defines which further procedures are to be carried out after a cell change, for example the implementation of the so-called CELL UPDATE procedure in a UMTS system for mobile radio terminals in RRC connected mode status CELL PCH.
- the above description of the prior art relates exclusively to the radio part (AS - Access Stratum) of a cellular mobile radio network.
- Further procedures and requirements for the behavior of mobile devices are provided by the core network behind the radio network (CN - Gore Network):
- the management of the mobility of a mobile device is managed by the core network or by the radio network depending on the status of the mobile station (idle vs connected mode).
- the term in the 3GPP technical standards for this is "mobility management" (MM - mobility management in the "Non Access Stratum” (NAS)).
- LA Location Areas
- RA Routing Areas
- the CS Circuit Switched core network
- MSC Mobile Switching Center
- RA routing areas
- LAU Loaction Area Update
- RAU Routing Area Update
- the core network has the option to reject a Loaction- or routing area update of a Mobilfunkent mars, where it tells the Mobilfunkent Competition the reason for refusal. This procedure is defined in [3GPP TS 24.008] and is called Location Registration Reject.
- [3GPP TS 24.008] also defines a number of disapproval reasons and the resulting consequences and requirements for a mobile terminal. Examples of procedures required by the mobile terminal in response to a LAU rejection include performing a PLMN selection upon receiving Reason # 13 (ie, searching for a new network operator (PLMN)), searching another neighbor cell within another Loaction / Routing Area on reception a refusal with reasons # 14 or # 15 etc. ... For details, please refer to [3GPP TS 24.008].
- Reason # 13 ie, searching for a new network operator (PLMN)
- PLMN new network operator
- a cell that is being used as a candidate for a potential cell change must belong to the currently used PLMN (ie have the same PLMN identity as the current cell - a peculiarity here is the concept of "equivalent PLMNs" (ePLMN) which underlies the mobile terminal certain conditions allowed in another PLMN to switch as if these neighbor cells belong to the current PLMN [TS 24.008]).
- ePLMN equivalent PLMNs
- the target cell may not be barred ("barred cell"), not reserved for an operator (only UMTS) ("operator reserved cell”) and ultimately not included in the "list of This list contains all the location area identities in which a location area update was once rejected for an initiated cell change.
- barred cell not reserved for an operator (only UMTS) ("operator reserved cell”
- list of This list contains all the location area identities in which a location area update was once rejected for an initiated cell change.
- a mobile terminal neither to GSM - According to UMTS standard in the current cell receives enough information about the neighboring cells to suppress the radio engineering surveying and the identification of the potential target cell.To recognize whether a neighboring cell - the ALL mobile devices as a potential target for a cell change using cell reselection was announced via the broadcast channel (BCCH) of the current cell - au If the required conditions for a cell change are met, the mobile radio terminal must synchronize with the potential target cell and read out its broadcast channel (BCCH) in order to obtain the necessary information (
- the object of the invention is to specify a method for optimizing the operational readiness times and cell change performance of mobile terminals, which offers the possibility that different mobile terminals use different neighborhood information (which was made available via the broadcast channel) for cell reselection, as well as corresponding arrangements for Indicate the implementation of the procedure.
- the invention is essentially based on the number of by the
- the present invention represents a substantial improvement of the prior art, since it makes it possible to avoid the radio-technological measurement of neighboring cells when a GSM or UMTS standard mobile radio terminal has already examined and determined this neighboring cell for its qualification as a potential target cell in that it is not suitable as a target cell for this mobile radio terminal.
- the proposed method mainly relates to the application in the case in which the target cell is not suitable for a cell change, since the access to this cell has already been rejected by a location or routing area update through the core network.
- the target cell belongs to another PLMN, for example, the target cell is marked as "blocked” or as "reserved for network operators".
- This national roaming agreement allows, for example, the customer of the operator B (PLMN B) in the areas of the operator A (PLMN A) to "roam" (ie to use mobile services operator A), where operator B offers no own mobile service.
- this embodiment provides that, for example, the operator A operates a mobile radio network according to both GSM and UMTS standards.
- This operator has configured his GSM network in such a way that a mobile radio terminal which supports both GSM and UMTS, in areas where it a UMTS supply of the operator A, automatically changes to UMTS, without the mobile user must intervene (UE based cell reselection) .
- This arrangement is shown in Figure 1.
- dual-mode mobile devices dual-mode UEs
- UMTS - ie devices that support both GSM and UMTS -
- the automatic change of so-called dual-mode mobile devices (dual-mode UEs) - ie devices that support both GSM and UMTS - is the radiation of neighborhood information on the UMTS network in the GSM network in the areas where a UMTS network is above the GSM network - allows.
- ALL dual-mode UEs follow the cell reselection (GSM-based cell change) from GSM to UMTS as soon as the UMTS network quality is sufficiently good.
- the exemplary national roaming agreement between operators A and B further provides that the customers of operator B may use the entire GSM network of operator A, but they do not have access to the UMTS part of operator A's network (even though the customers of operator B, who are in operator A's network, have a dual-mode UE, which would in principle support UMTS access).
- the requirement of the exemplary national roaming agreement thus provides that the access of the customers B (or only a certain part of these customers) to the operator A's UMTS network is prevented.
- this can be achieved by suppressing the access attempt of a mobile terminal of the customer of the operator B in the UMTS network of the operator A.
- operator A has configured his GSM / UMTS network so that the cells of the GSM and UMTS networks are located in different location areas (LA) and every change from GSM to UMTS and UMTS to GSM is a location Area Update abuts.
- LA location area
- the core network of the operator A now has the possibility to prevent the access attempt of a customer of B, for example in the location areas, which use the UMTS technology (or only a subset) by rejecting the Location Area Update (LAU) with a corresponding rejection code .
- LAU Location Area Update
- Today's implementation of this rejection procedure allows a differentiation of the mobile terminals about the origin (for example, based on the IMSI). The access can therefore be approved by A's customers, while B's customers are rejected.
- the prior art thus allows the rejection of the customer B - without UMTS access permission - in the UMTS network of A, by means of a rejection of the LAU.
- all dual-mode mobile terminals in the areas where operator A UMTS supply has a cell change from GSM to UMTS but only the mobile radio terminals of the operator A in the target UMTS Loaction Areas are allowed , the rejected mobile terminal of the operator B must abandon the cell change and remain in the original GSM cell.
- the main disadvantage of the prior art is the requirement that the potential target cells gem.
- the configuration on the broadcast channel of the current cell EVEN if access to that target cell is FORBIDDEN.
- a mobile station of operator B would remain in the GSM cells of operator A, but would have to comply with the requirements in the o.g. Specifications continue to measure the UMTS target cells that are not suitable for this mobile radio terminal. This requirement has significant negative effects on the standby time of the mobile station, since the unnecessary measurements mean additional energy consumption for the mobile station.
- the method according to the invention therefore suggests that a mobile terminal "notices" that access to a certain neighboring cell is not possible (for example, because the LAU in that cell has already been rejected) .
- a mobile terminal maintains a further additional list in which, for example, cell identities of cells ("Cell Id") or other characteristic features that uniquely identify a neighboring cell are noted, in which a LAU failed, or the cells that failed Mobile terminal, but they could not be used for a cell change since they belong to an LA included in the "Prohibited LA roaming list".
- Cell Id cell identities of cells
- characteristic features are, for example, the frequency of a neighboring cell in the case of GSM, the BSIC in a GSM neighboring cell, the scrambling code of a neighboring cell in UMTS, a carrier frequency in WLAN, an "SSID" in WLAN etc.
- the method according to the invention makes no restrictions whatsoever regarding the identity After this, a mobile station with the stored information could not measure the neighboring cells, which are not candidates for one anyway Cell exchanges are suitable, avoid, and thus prolong its Betzeitschaftszeit by the restriction to the actual possible neighboring cells by the unnecessary measurements are avoided.
- UMTS now locked
- An application of the invention is conceivable not only for mobile terminals according to GSM or UMTS standard, but also to other wireless network technologies (eg wireless LAN (W-LAN), cdma2000, WiMAX, WiBro, enhanced UTRAN, etc.) transferable.
- WLAN wireless LAN
- cdma2000 e.g., cdma2000, WiMAX, WiBro, enhanced UTRAN, etc.
